Read multiple records from a file and store it in a structure

Hi,
I need a program in C that is capable of writing the multiple records into a file.And another function that should read the same data from the from the file and store it in the approptiate data structure.

for eg:

Code:

typedef struct res
{
int res_type;
char *res_name;
char *res_loc;
int priority;
}res




int store(int g_id,char *gname,struct res)
{

all these parameters should be stored in a file
 
and return 1 if the storing is success
and 0 if the storing is failed

while storing if there is a repetition of g_id a error should be displayed.g id should be unique for each record
}


-----------------------------------------------------------------------------------------------------------------------------------------
inside the file, informations should be stored like this
-------------------------------------------------------------------------------------------------------------------------------------------
g id :100
g name:xyz
res type:s/w
res loc:c:/windows/pgm/a.txt
res name:asd

g id :210
g name:yzs
res type:s/w
res loc:c:/windows/pgm/a.txt
res name:acd

g id :101
g name:xss
res type:s/w
res loc:c:/windows/pgm/a.txt
res name:aza

------------------------------------------------------------------------------------------------------------------------------------------


struct read()
{

read should be capable of retrieving each record(i.e, g id,gname ,res type,res loc,res name) and store it in  a structure and should return the structure to the calling function

}

plz help me to get the code
